Option
Meaning
[OPT1] Subnet mask
32-bit address mask that displays which bits of the IP address
identify the network and which identify the network stations.
[OPT2] Time zone
Time difference between the local time and the UTC (Universal
Time Coordinated).
[OPT3] Gateway
IP address of the router that permits access to other networks.
[OPT6] DNS server
IP address of the name servers that converts a name into an IP
address. Up to 2 DNS servers can be configured.
[OPT12] Host name
The name of the host is the unique name of a computer in a
network. The host name can contain up to 32 characters.
[OPT15] Domain name
The name of the domain is the unique name of a network. The
domain name can contain up to 32 characters.

[OPT42] NTP server
IP address of the Network Time Server. When assigning an NTP
server, the SNTP client is automatically enabled in the coupler.

The "Features" WBM page can also be used to select the "BootP Request before
static IP" option. After the restart, 5 BootP queries are sent. If there is no response
to any of these queries, the fieldbus coupler/controller tries to configure itself with
the IP parameters saved in the EEPROM.
The network parameters (IP address, etc.) are stored in the EEPROM when using
the Bootstrap protocol to configure the node.
Note
BootP configuration is saved in the EEPROM!
Please note that the network configuration is stored in the EEPROM when using
BootP in contrast to configuration via DHCP.
By default, BootP is activated in the fieldbus coupler/controller.
When BootP is activated, the fieldbus coupler/controller expects the BootP server
to be permanently available.
If there is no BootP server available after a PowerOn reset, the network will
remain inactive.
To operate the fieldbus coupler/controller with the IP configuration stored in the
EEPROM, you must deactivate the BootP protocol after configuration.
The Web-based management system is used to deactivate the BootP protocol on
the respective fieldbus coupler/controller-internal HTML page under the "Port"
link.
If BootP is deactivated, the fieldbus coupler/controller uses the parameters saved
in the EEPROM when booting next.
If there is an error in the saved parameters, the I/O LED reports a blink code and
configuration via BootP is turned on automatically.
